Beskrivelse
Potassium hydrogen phthalate, also known as KHP, is a volumetric standard manufactured under stringent conditions and measured with the highest possible precision. Its mass fraction is determined by potentiometric titration, and it is qualified in a DIN EN ISO/IEC 17025 accredited laboratory. Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation. In our effort to be more sustainable, we′re going digital with COAs-download them directly from our website.
